I'm a chemist and once did a summer internship at a company that makes orange juice. I was surprised to see that MeOH is among the minor constituents of orange juice as well. There was a large problem at the beginning of the pandemic with unscrupulous vendors using methanol in hand sanitizers, too.
Thank God There is a professional educated person on here. ( STOP CONFUSING PEOPLE YOUR RESEARCH MUST BE FROM UA-cam, IF SO YOU ARE FOOLING PEOPLE!!!!!!!!
Indeed - I wrote an article for MSRC at the time about the dangers of non-judiciously produced hand sanitizer commonly used during the onset of the so called pandemic.
Yeah, at the distillery where I work the foreshots go back into the low wine and get redistilled. There is no real build-up of methanol, because the amount produced in fermentation of grain is so small, and methanol is also the quickest to evaporate off at ambient temperatures. Pretty much all the cases you hear of about methanol poisoning are due to very callous and heartless people mixing in industrial methanol into cheap, illegal spirits and thus getting greater profit.
Thank you for clarifying such stigmas, I had to search for these myself before. It was very helpful to hear them again, and I also learned some new points, thanks again
I question the concept that the "forces" acting on the alcohols are acting stronger on the methanol because of its lower pure boiling point, i feel this is more than offset by the significant difference in the relative polarity of methanol vs ethanol leading to stronger hydrogen bonds between methanol and water. This is shown in studies that show the concentration of methanol increasing through the distillation process and actually peaking in the tails cut. Even a good reflux still will see a tails peak and admittedly a heads peak too. In summary i feel the forces acting on the methanol are indeed stronger but those forces are hydrogen bonds preventing methanol from vaporizing. I welcome your feedback.
I used to work the pits for some Solo racing bike riders, some of the best in my country and Methanol is what's used in them. I used to get very angry if a spectator came near the bikes while I refueled them, because it's highly flammable. But you also see certain high alcohol drinks, set on fire 🔥 occasionally also.
Well done, Brewbird! You dispelled a number of long standing myths. Wine and beer contain methanol, be it small quantities. If you drink these fermented beverages you consume all the methanol produced. If the wine or beer it distilled some of the methanol can be discarded. Oranges juice naturally contains measurable amounts of methanol, I never touch the stuff straight only mixed with the antidote. Great video, thank you!
@@MissBrewbird better safe than sorry. In truth, the only way I drink orange juice (too much sugar) is with a good ouzo. Orange and anise pair so well, it is not widely known.
Hello, great video as always. I'm really glad you talked about the difficulty in 100% separating methanol because of hydrogen bonding but also explained why that's usually not something to worry about. I learned that methanol doesn't come out all in the fores from the Still Behind the Bench channel and I haven't seen anyone else mention this. So great job!!
Hi Brewbird, and thanks for this video. I have long researched and read articles about methanol, it's source in fermentation and how does it behave in distillation. The new information for me in your video was that apricots are among the low pectin containing fruits. I have always assumed the opposite. And now I'm wondering about persimmon specialy the goue ones that you have to age before you can eat. Any way back to your video, I was hoping that you discuss hydrogen bond with methanol, and is it true that in a pot still it changes methanol evaporation temperature? Thanks a lot for all you do and the efforts you put into your channel.
Great informative video. You mentioned your experience at the scotch whisky distillery about ageing the whiskey also helped with the evaporation of the methanol. Does it evaporate more readily than ethanol? Another good reason to age your spirits.
Great video! Have subscribed! I was wondering - does this mean if I re-distill shop bought vodka for instance, that I still need to take a cut to remove methanol? Or will the levels be so low (because the 1st distillation would have done that) that it wouldn’t make a difference?
Methanol boils at 148 IF it is pure, but when mixed with water and ethanol it is not 148 BUT evaporation takes place at room temperature (and lower). It is just that heat causes it to happen faster. It is volatile meaning the tendency to vaporize. Water will vaporize (evaporate) down to 33 degrees F but it takes a while. Add heat and it is faster. When water hits 212 F all of it does not turn to steam, and the same with methanol when you hit 148.
Thanks very much. The content of your video rescinates with me. Recently, I visited Dubai abd one night someone took me to a house. They were serving what they called Whiskey. Afterwards, i experienced all the symptoms you described
I was surprised to learn that methanol is present throughout distillation. I formerly believed I discarded all of it before my still got to 174F. Thanks
the government loves metho which is a combiniation of methanol and ethanol and can be used in household tasks such as cleaning without providing ethanol which can be drunk. Metho has a common boiling point (I forget the proportions) which means if you distil metho, you just get metho. If you need ethanol for laboratory use, you have to get a permit from Customs or I forget who does it now. I read that whiskey has to be aged in oak casks by law, this absorbs the poisonous alcohols, not sure if this is just methanol or includes the other alcohols.
I was most surprised to hear that an unclean fermentation can lead to higher methanol levels. I wonder how that applies to distilleries using wood fermentation vessels. Great video! Will definitely be referring people talking about removing ALL the methanol to this one so I can say "see, told you so!" LOL Always thought something was up with strawberries too, I noticed that when they're over-ripe that they taste of alcohol.
I don't think you can. Apparently a small % is part of the taste. .and if I'm right, the no BS Russian/Pole bathtub distillers have a booze that's EXTREMELY full of alcohol, but NO nasty kick. It's like water. You just KNOW a lot of people would kill themselves with that immediately. Not sure how that correlates to methanol, but I hear it smells like diesel.
I recently made some rum and took 1 litre of foreshots just to be sure I got all the methanol! Hi from Vancouver btw I really enjoy your videos. Maybe you can help me with doing a single malt one day! Cheers, Ian
I have read about a study which states that methanol is lowest in the Fore-shot but highest in the Tail. Kinda turns things upside down now, doesn't it? What are you thoughts on this?
Back here because of Laos 2024? As an ex street drinker now 15 years sober, I had to smile when you said: ‘You should die of ethanol poisoning long before you die of methanol poisoning’.
Nice, I’m pleased to now know I will die from Ethan Allen poisoning first before methanol poisoning…well done miss brew bird ,I think it’s the Asian glow ;)
Safety is a great reason to take the foreshots out , but the best reason is because most of us want the best spirit we can make and foreshots are disgusting . My whiskey/white dog is so pure that even excessive amounts produce almost no hangover. hobby distilled liquor is practically free , there is no reason to try to save a few pennies on wringing out an extra 50 Oz .
fascinating- I surprised that there may be ethanol in a well-controlled fermentation of apple juice- do I correctly assess that you advise the use of pectolase in musts prior to fermentation?
Hi! Yes, you can make ethanol in just about anything that has a sugar content eg milk, potatoes, fruits. I think scientifically speaking, using pectolase would assist in breaking down the pectin which would in turn increase the level of methanol produced. This methanol would concentrate during the distillation process. In real life, I have heard of pectolase being used as people have said it helps create a more flavoursome distillate.
hello and thank you for your great explanation , a question came to me that is there a way to determine the level of methanol poisonous in a drink that leads to blindness? as I don't trust the distillation process. I have heard that we can recognize a toxic methanol or ethanol drink by adding Boric Acid and watch burning flame of methanol is green and methanol is blue , I don't know that is true or not please help me :(
@@MissBrewbird Hi, I have a small auger mill that does the job. I don;t want to kiln the malt, as not to give it any flavour just want to rise the SG of my wine must/mash instead of using table sugar.
Hi Miss Brewbird, great video!! I am just dropping by to let you know I've sent you an e-mail about some questions I have in mind.. hope you have some time to read it!
I find it very surprising that bacteria too can produce methanol through fermentation. Till now I was under the impression that only yeast can do fermentation and only produce ethanol. Also, I did not know that fruit skins can be useful in making alcohol.
Any idea how it could be cheaper to produce methanol than ethanol? I find it hard to understand considering methanol production via gaseous hydronation of CO2 is much more complex to produce and more expensive than a natural fermentation process at small scale.
Nope. You're unlikely to inhale a toxic dose of methanol in a few seconds. Even if you did, its toxic effects are slow to manifest. It has to be metabolized into formic acid to cause methanol poisoning, and this is fairly slow - it takes hours after exposure for enough formic acid to build up to cause toxicity.
The highest % of cases of methanol poisoning come from inhalation in industrial settings, so don’t breathe the fumes coming out of your still before condensation starts, high % methanol.
Should be no "fumes" coming out of your still....just liquid. However, some stills allow for the venting of vapours out of the column...that might be of some concern.
I used to make my own moonshine but kept the heads and tails separately and redistilled them. I also used to leave the lid off the distilled moonshine for any ugly smell and any impurities to evaporate. I made the bet moonshine amongst all my peers and used a home made wash, I never got sick.
Thangs so much for this.. Is there no way or testing how pure the etanol is? If there is to much metanol. I made my alkohol from appels from now on i will get rid of more heads. Also i vent the still in the start up to 63degrees.. So most go out before maby... I cant smell the difference at least. LOL funny you say norway. Im form there ... Been a long time since i did destill it's so ilegal here. And i do it for fun. Dont even drink LOL.. But love to make it.
I'm sure you can test it in the lab, but if you are just in the distillery it's mostly a smell test. If you take a generous heads cut you should be okay.

Is the way of measuring methanol in a run?
The methanol is all throughout the run. I can't think of a quick way to measure it, aside from taking it to the lab.
I find it very surprising that bacteria too can produce methanol through fermentation. Till now I was under the impression that only yeast can do fermentation and only produce ethanol.
Also, I did not know that fruit skins can be useful in making alcohol.
Yup. See Pruno or jail made booze
where does the misinformation come from.........thanks for setting the record straight
probably the us government in prohibition times
Any idea how it could be cheaper to produce methanol than ethanol? I find it hard to understand considering methanol production via gaseous hydronation of CO2 is much more complex to produce and more expensive than a natural fermentation process at small scale.
It is not cheaper to produce but methanol is not taxed as a beverage. Ethanol is available at the gas station cheap.
Is it true if we smell/inhale methanol for a few second can cause us faint?
